The NRC gave itself a six-month deadline on the simplest contested reactor cases

The Nuclear Regulatory Commission finalized a rule on October 30, 2026 that sets a six-month target for resolving the simplest contested licensing hearings. Most contested cases are meant to finish in about a year, according to the agency, where hearings on reactor and other licensing applications have often run for years. Chairman Ho K. Nieh said the rule preserves public participation while making the hearing process more efficient.

The deadline applies to the contest, not to the safety review. Anyone who opposes a license application can ask for a hearing and raise contentions, and each admitted contention starts a clock. The new rule changes how fast that clock runs and which cases get the short version.

Three hearing tracks and a published finish date

The agency’s release 26-082 sorts contested hearings into Standard, Focused and Expedited tracks based on how complex an application is. The release does not say which track maps to which timeframe, only that firm schedules aim to finish most cases in about a year and the simplest in roughly six months. Every hearing notice must now carry a “Standard Hearing Completion Date,” so applicants, intervenors and the public all see when the NRC expects to be done.

The rule also changes when work starts. Hearings begin as soon as practicable after a contention is admitted, rather than waiting for the NRC staff to finish its technical review, and the two proceed side by side. The agency says running them in parallel saves months. It adds that the rule leaves licensing standards and its independent safety and security evaluations alone, and that it applies to contested hearing opportunities opening on or after the effective date, which falls 30 days after Federal Register publication.

The March proposal’s day counts and what is still unsaid

The final rule grows out of a proposal published at 91 FR 10450 on March 3, 2026. The proposed rule in the Federal Register did not use track names. It grouped proceedings by application type and gave each group a day count from notice to a decision on contentions: about 87 days for the most routine amendments, 77 for transfers, 112 for items such as license renewals and early site permits, and 127 for the most complex, including construction permits for new facilities without a referenced design. Its stated goal was to complete adjudications generally within 8 to 14 months, or faster for expedited proceedings.

It also proposed ending discretionary intervention, so a petitioner must have standing, and requiring that anyone other than an individual be represented by an attorney. Initial disclosures would be due 20 days after contentions are admitted instead of 30. The NRC put the cumulative savings for the agency and hearing participants at $51.7 million over 2026 to 2030. The release for the final rule does not say how many of those provisions survived, and the final text had not yet been published in the Federal Register when the release went out.

Several other pieces of the proposal went to the heart of how a hearing runs. Evidentiary hearings were to be resolved within a few months, appeals accelerated, and the burden of discovery reduced, while independent legal and technical judges would keep presiding over contested hearings. Later-filed challenges were not to delay licensing decisions unnecessarily, which the proposal handled through a Standard Record Closure Date after which new contentions face heightened reopening standards. Comments closed April 2, 2026 on docket NRC-2025-1501.

The ADVANCE Act and executive order clocks

Two outside pushes explain the timing. The NRC’s own page on streamlining the contested hearing process ties the work to the 2024 ADVANCE Act and to Executive Order 14300, which sets 18-month and 1-year decision deadlines for certain applications. The proposal added that the ADVANCE Act requires final decisions on certain combined licenses within 25 months of docketing and completion of required hearings within two years. A hearing that takes years cannot coexist with those clocks, so the rule goes after the hearing phase.

The American Nuclear Society’s report on the proposal framed it the same way, quoting the agency’s aim of meeting deadlines even when applications face hearing requests. The Breakthrough Institute, which backs the goal, took a more cautious line in April. Its energy innovation analyst Yue “Joy” Jiang wrote in comments on the proposal that streamlining is imperative but the final rule should be more coherent and workable in practice, urging clearer definitions and attention to how it interacts with the separate Part 51 and Part 53 rulemakings.

The test comes with the first contested case that opens under the new rule, when a Standard Hearing Completion Date appears on a notice and the Atomic Safety and Licensing Board either meets it or does not. The release also points to the final rule document in the NRC’s records system as ML26302A161, so the full track-by-track timelines can be checked against what the agency wrote.
